Can anyone identify the extra who appears behind Olivia Newton John 2mins24secs into the song "Summer Nights"?

Hi all. This is a very odd 질문 but one I hope 당신 can help me with. I am trying to track down one of the actors who appeared in Grease. He is an extra who had no lines but appears sitting on his own in the background during the song "Summer Nights" I have included a link to a 유튜브 clip of the song. The extra, who is a man, appears sitting on a 표, 테이블 in the schoolyard on his own just behind Olivia Newton John 2 분 and 24 초 into the song. He looks quite lonely, like he really needs a hug. I am 글쓰기 an 기사 on unrecognised extras in famous 영화 and would dearly like to get in touch with him. If anybody knows this actor's name 또는 can help I'd really appreciate it. Thank 당신 for all your help!
